So currently my system is 4.0. I have a phantom center, LFE is routed to the mains, and I have 2 rear/surround speakers. I'm wondering if I'll get more/better dimensionality by adding some side surround speakers. They'd be placed about ear level where the little cubes with a "?" indicate. Also, when the couch is full, I center it in the room so no one is sitting against the wall ;-) media_room by Barry, on Flickr Thoughts?
